ABSTRACT:
A call box (201) provides vandal-resistant operation by using a concealed magnetic switch and magnet (179) and specially locked compartments (101 and 103) in a heavy duty structure. The concealed magnetic switch determines the position of a handset (119) within the call box (201). When the handset (119) is removed from its resting position, a radio (129) within the call box (201) responds when a pushbutton (127) within the call box (201) is pressed. When the pushbutton (127) is pressed, telephone service is provided via a radio (129) to a preprogrammed phone number, such as the highway patrol for a call box (201) located on a highway, to handle situations such as a malfunctioning vehicle.
